(x-3)(x+4)=x^2+4

Solution

(x - 3) (x + 4) = x^{2} + 4

Solution

x = 16

Solution steps

(x - 3) (x + 4) = x^{2} + 4

Expand

(x - 3) (x + 4) : x^{2} + x - 12

x^{2} + x - 12 = x^{2} + 4

Move

12

to the right side

x^{2} + x = x^{2} + 16

Move

x^{2}

to the left side

x = 16

Popular Examples

- 2 x - 1 \leq 0

- 2 ∣ x + 4 ∣ + 16 = 0

2 y + 10 = - 2

3-(3x)/(x+1)>= 1/(x-1)

3 - \frac{3 x}{x + 1} \geq \frac{1}{x - 1}

\frac{k}{6} = \frac{15}{18}
